“I was really surprised, but you know what? There was a lot… that Carol said in that council meeting,” Melissa said. “This season and these scripts, there’s just not a word wasted and so I was reading that and remembering that council meeting and how she behaved with the children and the urgency of everything and then when I read that it was actually Carol that killed Karen and David, I was really surprised sort of, but then not surprised. You know?”

It was at the council meeting in last Sunday’s episode (402, ‘Infected’) where Carol let her views about the sickness be known.

“Just the words in the council meeting kept coming back to me — ‘If they die, they’re a threat. You die, you’re a threat.’ And there’s so much going on in the prison right now and these deaths from the flu are immediate, practically, and there is no cure in sight,” Melissa said of the hints that came before the big reveal. “But there was some great speculation going on around set as to who it could have been.”
